Bananiot,
I accept your observations on the current situation. Naturally it would be unlikely that a TC would become president in one generation. But why make the safeguards so as to include the provision that the president will always be a GC? In a unitary system as that envisaged in the Zurich treaty the ethnic division of the Presidency and Vice Presidency were understandable. In a Federal system where there is bizonality and bicommunality it is reasonable to expect all citizens to vote for the president if for no other reason than to have the highest office open to all citizens if not in practice at least in theory. ALso because under a BBF the safeguards are put in via other means and not just the ethnic origins of the two highest office holders.
In addition to the theoretical aspect there is the practical aspect that all presidential candidates would campaign for the votes of all ciitizens and thus encourage both communication and political cohesion. It might even make the TCs the most critical political force in Cyprus politics.
If we add to the above the reserving of the vice presidency for TCs, then there will be an automatic creation of the "joint ticket" which Christofias proposed in the talks, but without formalising the system in the constitution. How else would a GC politician address his TC voters if he does not have a TC partner? And how would he approach those voters if he did not look at their day to day problems. It will no longer be possible to ignore 18 per cent of citizens as was done in the past.
Of course the realistic way is to accept the division which is being built into the government system now negotiated. If we did not communicate sufficiently and did not pay attention to each other's communal problems when we lived in mixed village and towns one wonders how it will be under a bizonal system.
